Had been provided. This is because the dust collection chamber lid is opened and closed by rotating the dust collection chamber lid around the frontmost part of the division line. If this division line is provided below the top surface of the nozzle unit, the dust collection chamber lid is rotated and opened and closed. In some cases, the front part of the dust collection chamber lid was caught behind the center of the nozzle part and could not be opened and closed.

[0003]

In such a configuration,
The only way to increase the dust collection volume was to provide the upper end of the dust collection chamber lid higher or extend the frontmost part of the dust collection chamber lid forward.However, in the former case, the main body became large and the weight increased. There was a problem that the storage space in the box or the box was large, and in the latter case, when cleaning the bottom of the bed, the front part of the dust collection chamber lid was caught and did not enter the bed sufficiently. .

Accordingly, an object of the present invention is to provide a vacuum cleaner having a larger dust collection volume without increasing the height of the main body and the thickness in the front and rear directions.

[0005]

In order to achieve the above object, the present invention provides a motor chamber having a lower part and a motor chamber having a lower part.
A dust box having a dust collection chamber, and a motor chamber.

Further, the shape from the center of rotation of the dust collection chamber lid to the lower part of the dust collection chamber lid is provided in a concave shape with respect to the center uppermost portion of the nozzle portion.

[0007]

According to the above configuration, the dust collecting volume can be increased as the dust collecting chamber lid is enlarged. Further, when the dust collection chamber lid is opened and closed in this configuration, the distance from the rotation center of the dust collection chamber lid to the lowermost front portion of the dust collection chamber lid is from the rotation center of the dust collection chamber lid to the uppermost center of the nozzle portion. The dust collection chamber lid is longer than the distance to the front of the dust collection chamber lid, but the part from the center of rotation to the lower front part of the dust collection chamber lid always hits the uppermost part of the nozzle center. It doesn't mean that it can't be opened and closed by getting stuck behind the center.

Further, the shape from the rotation center of the dust collection chamber lid to the lower part of the dust collection chamber lid is provided in a concave shape with respect to the uppermost portion in the center of the nozzle portion. Since the shape always hits the uppermost part in the center of the nozzle portion, the opening / closing angle of the dust collection chamber lid can be made large and not only facilitates opening / closing, but also the concave shape induces attachment / detachment of the dust collection chamber lid.

As shown in FIG. 2, the distance D1 from the rotation center 11 of the dust collection chamber cover 5 to the lowermost front portion 8 of the dust collection chamber cover 5 is determined from the rotation center 11 of the dust collection chamber cover 5 to the nozzle section 6. It is provided so that D1> D2 with respect to the distance D2 to the central uppermost portion 9.

With the above construction, the dividing line between the dust collecting chamber lid 5 and the motor chamber lid 4 is provided below the top surface of the nozzle portion 6, and as the dust collecting chamber lid 5 is enlarged, the dust collecting volume is increased. Can be increased. When the dust collection chamber cover 5 is opened and closed in this configuration, the distance D1 from the rotation center 11 of the dust collection chamber cover 5 to the lowermost front portion 8 of the dust collection chamber cover 5 is determined by the rotation center of the dust collection chamber cover 5. 11 is longer than the distance D2 from the nozzle portion 6 to the uppermost portion 9 in the center of the nozzle portion 6, the portion from the center of rotation 11 to the lowermost front portion 8 of the dust collection chamber lid 5 is not the front surface of the dust collection chamber cover 5. As shown in FIG. 3, since the dust collecting chamber cover 5 always hits the uppermost portion 9 in the center of the nozzle 6, the dust collecting chamber lid 5 is not caught behind the center of the nozzle 6 and cannot be opened and closed.

Further, the shape from the center of rotation 11 of the dust collection chamber lid 5 to the lowermost front portion 8 of the dust collection chamber lid 5 is changed to the nozzle section 6.
It is provided in the concave shape 12 with respect to the central uppermost portion 9.

With this configuration, when the dust collection chamber cover 5 is opened and closed, the concave shape 12 always hits the uppermost portion 9 in the center of the nozzle portion 6, so that as shown in FIG. Not only makes it easier to open and close,
This concave shape 12 also serves as an invitation to attach and detach the dust collection chamber lid 5.
